没有规则来制作目标，.elf 需要答案

【问题标题】：No rule to make target, needed by .elf没有规则来制作目标，.elf 需要
【发布时间】：2015-10-23 14:17:05
【问题描述】：

我是新手，在构建我为 arduino 编写的代码时遇到了问题。当我尝试构建版本时，它会完成构建，但尽管出现了错误：

 make: *** No rule to make target `/home/jonas/Dokumente/Studium/7.', needed by `test123.elf'.

我完全不知道我能做些什么来解决这个错误

这就是我的 makefile 的样子

非常感谢您的帮助。

【问题讨论】：

您已将/home/jonas/Dokumente/Studium/7. 指定为输入，但您没有这样的文件
它不是“代码”，只是“代码”。代码是mass noun，不能与不定冠词组合。

标签： c++ makefile arduino target avr

【解决方案1】：

您不能在 makefile 中正确使用带空格的路径。它不会起作用。

你逃离空间的尝试没有达到你想要的效果。

您通常也不应该使用此类文件的完整路径。

这使得移动 makefile/目录（或在其他机器上使用它）变得不必要地困难。

只使用相对于当前目录的路径。
